Punishments like cutting salary for one/two days can be exercised for mistakes?

Using the word "Serious" is not good with this even you will not get good performance from remaining employees also try to realize them realization will create a good work environment. Still, if you would like to go with “Serious” Punishment Company may less honest employs also.

For the repeated mistake after giving mild punishments a fine can be imposed. But it should be supported by the documents-charge sheet - domestic enquiry- findings to the extent that the alleged charges have been proved- order for the fine. Also the amount of fine is to be sent to welfare board and should be entered in the registered of fines.

Thank you for your inputs. We are also considering more awards for efficient working. Eligibility of such awards will be affected if such errors are committed repeatedly

Thanks all for your inputs. After going through the positive comments here, we are also considering more awards and link eligibility of such awards to not committing repeated mistakes. Non conformities can be logged and trended.

Punishments are a part and parcel of every administration,but positive inducements/recognitions are more powerful weapons in administration.
Punishments should be inflicted only after following due process and hearing the wrong doer.
Punishment system should be fair.
Similarly have a reward and recognition system which recognises true merit,achievement.
This is a positive tool in the hands of management.
Recognise the achievers in public.
Others will get inspired to do better.
